Mowing frequency should be increased during rapid growth periods because grass tends to grow more quickly due to optimal conditions such as warm weather, adequate moisture, and nutrients. When grass is growing rapidly, it can reach its ideal height more quickly, which can lead to increased competition for light, water, and nutrients among plants if not trimmed back. Additionally, mowing regularly during these times helps maintain a healthy lawn, encourages denser growth, and minimizes the risks of pest infestations and disease. Keeping the grass at the appropriate height also enhances its resilience and ability to withstand stressors.

Focusing on the other options, during periods of drought, it's generally advisable to reduce mowing to help conserve water and avoid stressing the grass. Mowing when the grass is dry can lead to uneven cut and can stress the grass further. In preparation for winter, the mowing frequency might decrease as growth slows down, and the final mow of the season typically involves cutting the grass slightly shorter to reduce the risk of snow mold or other winter diseases.
